For Glo subscribers, hiding one’s caller ID is as simple as dialling the code #31# before the number you wish to call. For example, if you are calling someone with the ID 0902898989, you would dial #31#0902898989 on your phone to hide your number from the call recipient.

Keep in mind that this is a per-call method, meaning that you will have to dial the #31# prefix anytime you need to hide your ID.

9mobile was formerly known as Etisalat Nigeria and was established in March 2008. The company is privately owned and operates on a Unified Access Service License from the Nigerian Federal Government.

To disable your caller ID on 9mobile, the steps are pretty much similar to those of doing so on Airtel and Glo. Dial #31# followed by the number you intend to call. Press the call button, and your ID will be effectively hidden from the person you are calling.

Do not forget to do this every time you need to hide your ID since the step only works once per call.

Ask your carrier to disable your caller ID

If you do not want to insert prefixes or go through your device settings to hide your caller ID, you could always ask your mobile carrier to disable your caller ID for you. You will need to place a request with the carrier’s customer care through the official support line.

If you run into call rejection problems because of the disabled caller ID, feel free to ask customer support to reenable your ID. Keep in mind that most carriers only allow ID hiding on local calls. International calls might have stricter regulations requiring callers to have their identity displayed.

Here are some of the most common reasons for hiding one’s ID.

  • Protecting personal information: People with ill motives can do quite a lot with your phone number in this day and age. You could easily become a victim of caller spoofing schemes, information breaches, and other unwanted scenarios. To avoid this, you may want to hide your ID when calling people that might contribute to a breach of your privacy.
  • Making an anonymous call: Calling anonymously might come in handy when reporting something you have witnessed, such as an ongoing crime. In this case, you can pass the information to the relevant authorities without showing your ID.
  • Using your work number: When using your work phone, you may not want the ID out there when using a work-issued cell phone. Having your work phone ID showing might result in unwanted calls during your work hours.
  • Calling telemarketers: If you have been receiving incessant calls from telemarketers, you might one day decide to call them back using a different number and ask them to remove your primary contact from their call list. However, doing this with the new number exposed might result in both numbers remaining on the telemarketing list.
  • Calling from a friend’s or minor’s phone: When using another person’s phone, neither party wants unwanted calls from the dialled numbers. This also applies when making calls using a minor’s phone. Hiding the ID ensures that the call recipient does not get access to the child’s contact.
